使用角色 apache

1. 建立 playbook apache.yml，群組 webservers 使用角色 apache。

   [deyu1@kvm19 ansible]$ vim apache.yml
   [deyu1@kvm19 ansible]$ cat apache.yml 
   ---
   - name: use role
     hosts: webservers
     roles:
     - apache
   

2. 執行 playbook apache.yml，成功完成任務。

   [deyu1@kvm19 ansible]$ ansible-playbook apache.yml 
   
   PLAY [use role] ****************************************************************
   
   TASK [Gathering Facts] *********************************************************
   ok: [kvm14]
   ok: [kvm13]
   
   TASK [apache : install the latest version of Apache] ***************************
   changed: [kvm14]
   changed: [kvm13]
   
   TASK [apache : Start service httpd] ********************************************
   changed: [kvm14]
   changed: [kvm13]
   
   TASK [apache : firewalld] ******************************************************
   changed: [kvm14]
   changed: [kvm13]
   
   TASK [apache : Template a file] ************************************************
   changed: [kvm14]
   changed: [kvm13]
   
   PLAY RECAP *********************************************************************
   kvm13 : ok=5 changed=4 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
   kvm14 : ok=5 changed=4 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
   

3. 測試連線。

   [deyu1@kvm19 ansible]$ curl http://kvm14/
